example 12
[0295]Renewable linear alkyl benzene and renewable detergent alcohol production using the renewable linear paraffin product of example 3. The renewable linear paraffin product of Example 3 is provided to a gas removal unit (FIG. 2, 9) to remove volatile gases and short chain hydrocarbons and then is provided to a standard petroleum refining fractionation unit (FIG. 2, 10) to provide three cuts of paraffins—C10-13 (cut 1), C14-16 (cut 2), and C17-C18 (cut 3). Cut 1 is sent to a dehydrogenation unit (FIG. 2, 13) and then to an alkylation unit (FIG. 2, 14), where it is alkylated with benzene to provide a renewable (partially, petrol-based benzene) alkyl benzene. Procedures to remove benzene and heavy distillate from the renewable alkyl benzene product are known to one skilled in the art. Cut 2 is sent to another dehydrogenation unit (FIG. 2, 15) followed by the step of olefin absorptive separation to provide a high purity renewable linear olefin mixture, which is further subjected to a...

example 14
[0297]Renewable linear alkyl benzene sulfonate. The renewable linear alkyl benzene product of example 13 is sulfonated in a standard falling film sulfonator unit and subsequently neutralized providing a renewable linear alkyl benzene sulfonate surfactant.
